    Hi All,
    Just joined the forums. I've inherited a 89 Chrysler 5th Ave. with 54,000 orig miles. I've been driving it for about 5 months now. I've always had trucks but I love the quiet cushy ride this car has. One problem though..A/C & Heater is stuck in the A/C position. I verified strong coolant flow through the heater core. The Automatic Climate Control dash unit is working properly and all vacuum lines and wiring are in place correctly. The potentiometer on the dash unit shows within specs. I want to know where the blend door motor is located on this. I think it has failed or is stuck. It's getting colder up here in the northeast. I'll need heat to defrost the windows. Will this job require a ton of tear down on the dash and heater unit to replace? Hope I can find an answer or two here, Thanks! -Brian :)
